Hi folks,
I just started getting this error all of a sudden (command line
snippet):
vmac:~/workspace/eir vince$ ruby -v
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]
vmac:~/workspace/eir vince$ rails -v
Rails 1.0.0
vmac:~/workspace/eir vince$ gem -v
0.8.11
vmac:~/workspace/eir vince$ ./script/server
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in

from ./script/…/config/boot.rb:16

vmac:~/workspace/eir vince$
Is anybody else having the same issue? Any clues as to what may be
wrong?
I did nothing to my environment, but the problem started after Mac OS X
notified me that updates were available and I started them in the
back-ground.
These instructions seem to have fixed the problem:

Yes, but you may have to tinker around with RMagick/imagemagick. I
would guess that your image is being split into its component frames
as its being resized, and the command to merge the frames back into an
animation is not being given. So that’s a bug you’ll have to get
past, but then it should work.

thanks for reply kyle
now i just use Magick::ImageList instead of Magick::Image and it seems
to work
so the class BaseUploadedFile looks something like this:
class BaseUploadedFile # :nodoc:
def transform_with_magick
if needs_resize?
begin
imglist = ::Magick::ImageList.new(absolute_path)
rescue ::Magick::ImageMagickError
@magick_errors ||= []
@magick_errors << “invalid image”
return
end
...
end
end
...
def resize_image(imglist, img_options, dest_path)
begin
if img_options[:crop]
dx, dy = img_options[:crop].split(':').map { |x| x.to_f }
w, h = (imglist.first.rows * dx / dy), (imglist.first.columns
dy / dx)
imglist.each do |img|
img.crop!(::Magick::CenterGravity, [img.columns, w].min,
[img.rows, h].min)
end
end
if img_options[:size]
size = img_options[:size].split("x")
xres = imglist.first.columns
yres = imglist.first.rows
if xres > size[0].to_i || yres > size[1].to_i
imglist.each do |img|
img.change_geometry!(img_options[:size]) do |c, r, i|
i.resize!(c, r)
end
end
end
end
ensure
imglist.write dest_path
File.chmod options[:permissions], dest_path
end
end
end
